Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a type of humidifier that blows air through a water absorption filter to vaporize it.

This type of humidifier has the fundamental drawback that the amount of humidified air is small because a water film and large-diameter particles remain on the surface of the filter that absorbs water, increasing air blowing resistance.

Furthermore, even if the amount of air blown by a large fan was increased, vaporization through the filter would not be sufficient, and the air would not be sufficiently humidified.

However, in order to create sufficiently humidified air, the fan and filter had to be made larger, making the whole thing larger.

The present invention has been made in view of the above points, and embodiments thereof will be described below with reference to the drawings.

1 is a box-shaped humidifier with a water tank 2 at the inner bottom, and a motor 4 is fixed to the upper part of the body with a horizontal beam 3 as a bridge.

Reference numeral 5 indicates an intake opening opened on the top surface of the vessel, and reference numeral 6 indicates an air outlet opening opened on both sides of the vessel below the horizontal crosspiece 3. It consists of a ventilation path 7 that leads to.

8 is a fan connected to the rotating shaft 9 above the motor 4;
It is disposed inside the intake opening 5 and forces air into the air passage 7 from the intake opening 5.

Reference numeral 10 denotes a lattice-shaped cylindrical drum with upper and lower openings connected to the middle of the rotating shaft 11 below the motor 4, and a cylindrical filter 1 having water absorption and air permeability such as non-woven fabric on the outer wall.
2 is for installation.

Note that this filter 12 has a predetermined thickness, and its lower end reaches the water surface of the water tank 2.

Reference numeral 13 denotes a pump in the shape of an inverted conical cylinder connected to the lower end of the lower rotating shaft 11, whose lower end plunges into the water of the water tank 2, sucks up water by rotation, and pumps it through the upper and lower discharge holes 14 in the upper part. Water is supplied by sprinkling water on the inner surface of the filter 12.

Reference numeral 15 denotes a guide cylinder vertically installed from the lower part of the horizontal beam 3 toward the upper end of the filter 12, and constitutes a part of the air blowing passage 7.

Thus, when the motor 4 is driven, the fan 8, filter 12, and pump 13 rotate at high speed, and air is first blown into the air passage 7, and especially from inside the filter 12 to the outside.

Then, the pump 13 sucks up the water and sprinkles and supplies water to the filter 12, and the filter 12 sequentially moves the water continuously supplied to the inner surface from the inside to the outside by centrifugal force to penetrate inside the filter 12. In addition, the centrifugal force is constantly applied to the entire structure, greatly reducing the resistance to air blowing.

Therefore, the amount of air passing through the filter 12 is increased, and at the same time, the air is sufficiently humidified through the vaporized water moving in the same direction.

This large amount of sufficiently humidified air is then blown through the air outlet 6.
It is blown into the room.

Incidentally, since the pump 13 and the filter 12 rotate at the same speed as the fan 8, the relative positions of the discharge holes 14 of the pump 13 and the opposing inner surface of the filter 12 remain unchanged. Water sprinkling and water supply from ... may not be performed on the entire inner surface of the filter 12.

Therefore, the perforation positions of the upper and lower discharge holes 14 are provided in a staggered manner, and the discharge holes 14 are connected to the filter 12.
It is desirable that the entire inner surface of the

In this way, the humidifier according to the present invention has an air passage that penetrates the cylindrical filter from the inside to the outside, and also rotates this filter, so that the water supplied to the filter can be transferred inside the filter. It is possible to remove air blowing resistance due to a water film on the surface and large-diameter particles by permeating the filter, and by constantly exerting centrifugal force on the filter, air blowing resistance can be reduced, thereby increasing the amount of air blowing without increasing the size.

In addition, since the supplied water is constantly moving inside the filter, it can be brought into sufficient contact with the air and can sufficiently humidify the air.
